On the 2008 and newer E90/E92 M3, the front pair of catalytic converters absolutely ROB the engine of horsepower and torque. We can help you GET THIS POWER BACK on your track/race only M3. Our custom tuned software allows you to remove the front cats (either by modifying your existing manifolds or running race headers) and make the most power possible. We did a before and after dyno, and saw a whopping +40 hp @ 8000 rpm and +32 lb/ft @ 3,000 rpm.... AT THE WHEELS!
Our Stage 2 software for the E90/E92 M3 makes use of the same features of our street legal Stage 1 software, as well as accounts for the front cat delete. We optimize timing and vanos, remove the top speed limiter, disables rear O2 sensors (for no check engine light or limp mode), and increases the rev limit by +300 rpm (optional). The stock rev limit is 8300, and we have found we can safely increase the rev limit to 8600.
